1. FIELD OF THE INVENTION

The present invention relates to a cooling system.

2. BACKGROUND

In a cooling system mounted on a compression refrigerator or the like,the refrigerant compressed by the compressor is radiated by theradiator.

Conventionally, a radiator, a cooling fan, and a compressor are disposedon the same line in a machine room of a refrigerator/freezer. Theradiator is installed upstream of the cooling fan. The compressor isprovided downstream of the cooling fan.

Conventionally, the compressor and the centrifugal fan are disposed inthe machine room of the refrigerator. The condenser is installed infront of the machine room, and communicates with the spiral casing ofthe centrifugal fan through a duct. The centrifugal fan blows windsucked from the condenser side to the compressor. The intake directionand the exhaust direction of the centrifugal fan are parallel to theinstallation face of the compressor.

When space-saving is implemented for the machine room, the storage spaceof the refrigerator becomes wider. However, in order to save space inthe machine room, it is necessary to reduce the size of the fan.However, there is a possibility that the cooling efficiency of theradiator and the compressor may decrease due to a decrease in theairflow amount of the fan.

DETAILED DESCRIPTION

Example embodiments are described below with reference to the drawings.

In the present specification, in a cooling system 100, a directionparallel to the direction normal to a fourth inner face 41 d, which willbe an installation face of a compressor 2 described later, is referredto as a “first direction D1”. Also, two directions in a plane orthogonalto the first direction D1 are referred to as a “second direction D2” anda “third direction D3”. The first direction D1, the second direction D2,and the third direction D3 are orthogonal to each other.

Of the first direction D1, the direction from an intake port 32 a of ablower 3 to be described later to a radiator 1 to be described later isreferred to as “one of the first direction D1 a”, and the direction fromthe radiator 1 to the intake port 32 a of the blower 3 is referred to as“the other of the first direction D1 b”.

Of the second direction D2, the direction from the blower 3 to thecompressor 2 is referred to as “one of the second direction D2 a”, andthe direction from the compressor 2 to the blower 3 is referred to as“the other of the second direction D2 b”.

Of the third direction D3, the direction from the radiator 1 to a thirdinner face 41 c of an accommodation chamber 41 to be described later isreferred to as one of the third direction D3 a″, and the direction fromthe radiator 1 to a second inner face 41 b of the accommodation chamber41 is referred to as “the other of the third direction D3 b”.

In a blower 3, the direction parallel to a rotation axis RA is referredto as an “axial direction”. The direction orthogonal to the axialdirection is referred to as a “radial direction”. Of the radialdirection, a direction approaching the rotation axis RA is referred toas “inward”, and a direction away from the rotation axis RA is referredto as “outward”.

In this specification, in the positional relationship between one andthe other among azimuth, line, or surface, “parallel” includes not onlya state where they never cross but also a state where they aresubstantially parallel. Further, “orthogonal” and “perpendicular”include not only a state where they intersect each other at 90 degrees,but also a state where they are substantially orthogonal and a statewhere they are substantially perpendicular. That is, “parallel”,“orthogonal”, and “perpendicular” include a state where there is anangle shift in the positional relationship between them withoutdeparting from the gist of the present disclosure.

In addition, when one intersects the other among azimuth, line, orsurface, and the angle formed by them is not 90 degrees, it is expressedthat they intersect at an acute angle. This expression is synonymouswith the fact that they intersect at an obtuse angle from a geometricpoint of view.

The cooling system 100 according to the example embodiment is part of acooling cycle unit mounted on, for example, a refrigerator. However, theuse of the cooling system 100 is not limited to this example. Thecooling system 100 includes the radiator 1, the compressor 2, the blower3, the cabinet 4, and the partition 5.

The radiator 1 releases the heat of a refrigerant 11 flowing inside theradiator 1 to the surrounding air, and in particular releases it to theairflow suctioned into the blower 3. As the refrigerant 11, for example,alternative chlorofluorocarbon, isobutane, or the like is used. Asdescribed above, the cooling system 100 includes the radiator 1.

The compressor 2 compresses the refrigerant 11 and sends it to theradiator 1. As described above, the cooling system 100 includes thecompressor 2.

The blower 3 includes a motor (not shown), an impeller 31, and a housing32. The motor rotation drives the impeller 31. The impeller 31 has aplurality of blades (reference numeral omitted) that can rotate aroundthe rotation axis RA. The housing accommodates the motor and impeller 31in its inside. The housing 32 has the intake port 32 a and an exhaustport 32 b. The intake port 32 a is provided on one side face of thehousing 32 in the first direction D1, and is directed to the one of thefirst direction D1 a. The exhaust port 32 b is provided on the side faceof the housing 32 in the radial direction, and is directed to the one ofthe second direction D2 a. The blower 3 is a centrifugal fan in thepresent example embodiment, but is not limited to this example, and maybe a blower having a pressure ratio larger than that of the centrifugalfan. The pressure ratio is the ratio of the maximum pressure of air thatcan be exhausted at the exhaust port 32 b to the pressure of air takenin at the intake port 32 a.

The blower 3 sends, by the rotation by the impeller 31 around therotation axis RA extending in the first direction D1, the airflowsuctioned from the intake port 32 a directed to the one of the firstdirection D1 a out from the exhaust port 32 b directed to the one of thesecond direction D2 a. As described above, the cooling system 100includes the blower 3. In the present example embodiment, the firstdirection D1 is parallel to the direction normal to the installationface on which the compressor 2 is installed. Further, the seconddirection D2 is orthogonal to the first direction D1.

The cabinet 4 is part of a main body cabinet of a refrigerator, forexample. The cabinet 4 has the accommodation chamber 41 and a vent 42.

The accommodation chamber 41 is a machine room of a refrigerator, forexample. The accommodation chamber 41 accommodates the radiator 1, thecompressor 2, and the blower 3. As described above, the cabinet 4 hasthe accommodation chamber 41, and the cooling system 100 includes thecabinet 4.

The shape of the accommodation chamber 41 is a rectangularparallelepiped shape in the present example embodiment. Theaccommodation chamber 41 is surrounded by the six inner faces composedof a first inner face 41 a, the second inner face 41 b, the third innerface 41 c, the fourth inner face 41 d, a fifth inner face 41 e, and asixth inner face 41 f. The cabinet 4 includes the first inner face 41 a,the second inner face 41 b, the third inner face 41 c, the fourth innerface 41 d, the fifth inner face 41 e, and the sixth inner face 41 f. Thefirst inner face 41 a is an inner face directed to the other of thefirst direction D1 b. The second inner face 41 b is an inner facedirected to the one of the third direction D3 a. The third inner face 41c is an inner face directed to the other of the third direction D3 b.The fourth inner face 41 d is an inner face directed to the one of thefirst direction D1 a. The fifth inner face 41 e is an inner facedirected to the other of the second direction D2 b. The sixth inner face41 f is an inner face directed to the one of the second direction D2 a.

The vent 42 is provided in the fifth inner face 41 e of theaccommodation chamber 41. The vent 42 penetrates the cabinet in thesecond direction D2. The accommodation chamber 41 communicates with theoutside of the cabinet 4 through the vent 42. In the present exampleembodiment, in the second direction D2, the vent 42 faces the exhaustport 32 b of the blower 3 with the compressor 2 interposed therebetween.Therefore, the airflow discharged from the exhaust port 32 b and coolingthe compressor 2 easily flows out of the cabinet 4 through the vent 42.In the present example embodiment, another vent (reference numeralomitted) similar to the vent 42 is provided on the third inner face 41c. However, the inner face on which other vents are provided is notlimited to this example. The other vent can be provided on at least oneof the inner faces of the accommodation chamber 41 other than the fifthinner face 41 e.

The partition 5 partitions the accommodation chamber 41 in the seconddirection D2. In the present example embodiment, the partition 5 has aplate shape extending in the first direction D1 and the third directionD3. In the accommodation chamber 41, the compressor 2 is disposed in thespace in the one of the second direction D2 a relative to the partition5. Further, the radiator 1 and the blower 3 are disposed in the space inthe other of the second direction D2 b relative to the partition 5.

In particular, in the second direction D2, the partition 5 partitions atleast part of a space between the radiator 1 and the compressor 2. Thecooling system 100 includes the partition 5 as described above. Thepartition 5 includes a plate-like panel 51 that intersects the seconddirection D2. In the present example embodiment, the panel 51 isorthogonal to the second direction D2. However, the present disclosureis not limited to this example, and the panel 51 may intersect thesecond direction D2 at an acute angle.

The partition 5 overlaps with the radiator 1 when viewed from the otherof the second direction D2 b. Preferably, as shown in FIG. 2, thepartition 5 overlaps with the entire radiator 1 when viewed from theother of the second direction D2 b. In the present example embodiment,the panel 51 overlaps with the entire radiator 1 when viewed from thesecond direction D2. Since the panel 51 overlaps with the entireradiator 1, it is possible to prevent the airflow blown from the blower3 to the compressor 2 from flowing to the surroundings of the radiator1. Therefore, it is possible to prevent the airflow that has cooled thecompressor 2 from returning to the surroundings of the radiator 1.Therefore, the blower 3 can cool the radiator 1 more efficiently.

The panel 51 has an opening 51 a. The opening 51 a penetrates the panel51 in the second direction D2. The opening 51 a communicates with theexhaust port 32 b. Therefore, the inside of the housing 32 of the blower3 is connected via the opening 51 a and the exhaust port 32 b with thespace where the compressor 2 in the one of the second direction D2 arelative to the panel 51 in the accommodation chamber 41 is disposed.Therefore, the airflow sent out from the exhaust port 32 b flows towardthe one of the second direction D2 a through the opening 51 a.

As shown in FIGS. 1 and 2, the panel 51 is provided between the blower 3and the inner face of the accommodation chamber 41 in a directionorthogonal to the second direction D2. More specifically, the panel 51is provided between the blower 3 and the first inner face 41 a, of theaccommodation chamber 41, that is directed to the other of the firstdirection D1 b. In the present example embodiment, part of the panel 51is provided between the housing 32 of the blower 3 and the first innerface 41 a of the accommodation chamber 41. Note that the presentdisclosure is not limited to the example of the present exampleembodiment, and the entire panel 51 may be provided between the blower 3and the first inner face 41 a. Preferably, as in the present exampleembodiment, part of the panel 51 is further provided between the housing32 of the blower 3 and the second inner face 41 b and the third innerface 41 c of the accommodation chamber 41. In addition, when there is agap between the housing 32 of the blower 3 and the fourth inner face 41d near the exhaust port 32 b, preferably, another part of the panel 51is provided between the two. By providing the panel 51 between theblower 3 and the inner face 41 a of the accommodation chamber 41, it ispossible to prevent the airflow that has cooled the compressor 2 fromreturning to the surroundings of the radiator 1 and to the intake port32 a of the blower 3. Therefore, the blower 3 can cool the radiator 1and the compressor 2 more efficiently.

In addition, in the direction orthogonal to the second direction D2, theend of the plate-like panel 51 is directly connected to at least one ofthe blower 3 and the inner face of the accommodation chamber 41.

More specifically, the end of the panel 51 in the first direction D1 ispreferably directly connected to at least one of the first inner face 41a and the end of the blower 3 in the one of the first direction D1 a.

For example, the end of the panel 51 in the one of the first directionD1 a is preferably directly connected to the first inner face 41 a asshown in FIGS. 1 and 2. Therefore, it is possible to prevent the airflowthat has cooled the compressor 2 from passing between the panel 51 andthe first inner face 41 a in the first direction D1, and returning tothe surroundings of the radiator 1 and to the intake port 32 a.

Further, in the opening 51 a, the end of the panel 51 in the one of thefirst direction D1 a is preferably directly connected to the housing 32of the blower 3 near the exhaust port 32 b as shown in FIGS. 1 and 2.Therefore, it is possible to prevent the airflow that has cooled thecompressor 2 from passing between the opening 51 a of the panel 51 andthe exhaust port 32 b of the blower 3 in the first direction D1, andreturning to the surroundings of the radiator 1 and to the intake port32 a.

Further, the end of the panel 51 in the third direction D3 orthogonal tothe first direction D1 and the second direction D2 is preferablydirectly connected to at least one of the second inner face 41 b, of theaccommodation chamber 41, that is directed to the one of the thirddirection D3 a, the third inner face 41 c, of the accommodation chamber41, that is directed to the other of the third direction D3 b, and theend of the blower 3 in the third direction D3.

For example, the end of the panel 51 in the one of the third directionD3 a is preferably directly connected to the third inner face 41 c asshown in FIGS. 1 and 2. Therefore, it is possible to prevent the airflowthat has cooled the compressor 2 from passing between the panel 51 andthe third inner face 41 c in the third direction D3, and returning tothe surroundings of the radiator 1 and to the intake port 32 a.

Further, the end of the panel 51 in the other of the third direction D3b is preferably directly connected to the second inner face 41 b asshown in FIGS. 1 and 2. Therefore, it is possible to prevent the airflowthat has cooled the compressor 2 from passing between the panel 51 andthe second inner face 41 b in the third direction D3, and returning tothe surroundings of the radiator 1 and to the intake port 32 a.

Further, in the opening 51 a, the end of the panel 51 in the one of thethird direction D3 a and the end of the panel 51 in the other of thethird direction D3 b is preferably directly connected to the housing 32of the blower 3 near the exhaust port 32 b as shown in FIGS. 1 and 2.Therefore, it is possible to prevent the airflow that has cooled thecompressor 2 from passing between the opening 51 a of the panel 51 andthe exhaust port 32 b of the blower 3 in the third direction D3, andreturning to the surroundings of the radiator 1 and to the intake port32 a.

In addition, when there is a gap between the housing 32 of the blower 3and the fourth inner face 41 d near the exhaust port 32 b, preferably,the end of the panel 51 in the first direction D1 is directly connectedto at least one of the fourth inner face 41 d and the end of the blower3 in the other of the first direction D1 b.

For example, between the housing 32 and the fourth inner face 41 d, theend of the panel 51 in the other of the first direction D1 b ispreferably directly connected to the fourth inner face 41 d as shown inFIGS. 1 and 2. Therefore, it is possible to prevent the airflow that hascooled the compressor 2 from passing between the panel 51 and the fourthinner face 41 d in the first direction D1, and returning to thesurroundings of the radiator 1 and to the intake port 32 a.

Further, between the housing 32 and the fourth inner face 41 d, the endof the panel 51 in the other of the first direction D1 b in the opening51 a is preferably directly connected to the housing 32 of the blower 3near the exhaust port 32 b as shown in FIGS. 1 and 2. Therefore, it ispossible to prevent the airflow that has cooled the compressor 2 frompassing between the panel 51 and the blower 3 in the first direction D1,and returning to the surroundings of the radiator 1 and to the intakeport 32 a.

Next, the arrangement of the radiator 1, the compressor 2, and theblower 3 in the accommodation chamber 41 will be described withreference to FIGS. 1 and 2.

In the present example embodiment, the first inner face 41 a of theaccommodation chamber 41 is a ceiling face, of the accommodation chamber41, that is directed vertically downward. The fourth inner face 41 d isthe bottom face, of the accommodation chamber 41, that is directedvertically upward, and is orthogonal to the vertical direction. Thecompressor 2 is installed on the fourth inner face 41 d. That is, in thepresent example embodiment, the fourth inner face 41 d is aninstallation face of the compressor 2 and is parallel to the horizontalplane. The definitions of these faces are definitions for use in thedescription in the present specification, and do not indicate the faceswhen incorporated in an actual device.

In the present example embodiment, the fourth inner face 41 d isorthogonal to the rotation axis RA of the blower 3. That is, in thisexample embodiment, the blower 3 is placed horizontally on a horizontalplane. The rotation axis RA is parallel to the vertical direction. Theblower 3 sucks air from vertically above and sends out the airflow in adirection parallel to the horizontal plane.

The radiator 1 is disposed in the one of the first direction D1 arelative to the blower 3. In the present example embodiment, theradiator 1 is disposed vertically above the blower 3. Preferably, theradiator 1 faces the intake port 32 a of the blower 3 in the firstdirection D1, and overlaps with the intake port 32 a when viewed fromthe first direction D1. More preferably, the radiator 1 overlaps withthe entire intake port 32 a when viewed from the first direction D1. Thecompressor 2 is disposed in the one of the second direction D2 arelative to the radiator 1 and the blower 3. Preferably, the compressor2 faces the exhaust port 32 b of the blower 3 in the second directionD2, and overlaps with the intake port 32 a when viewed from the seconddirection D2. More preferably, when viewed from the second direction D2,one of the compressor 2 and the exhaust port 32 b overlaps with theentire of the other. Further, the blower 3 is disposed in the other ofthe first direction D1 b relative to the radiator 1, and is disposed inthe other of the second direction D2 b relative to the compressor 2.

By disposing the radiator 1 vertically above the blower 3 and disposingthe compressor 2 in the one of the second direction D2 a relative to theradiator 1 and the blower 3, the blower 3 that sucks an airflow from theone of the first direction D1 a and sends out the airflow to the one ofthe second direction D2 a and the radiator 1 and the compressor 2 cooledby the blower 3 can be disposed in a compact manner. Therefore, thewidth of the cooling system 100 in the first direction D1 can be furtherreduced without requiring downsizing of the blower 3. Therefore, thespace of the cooling system 100 can be saved without reducing the amountof air blown by the blower 3.

Further, a distance Dh in the first direction D1 between the end of theradiator 1 in the one of the first direction D1 a and the end of theblower 3 in the other of the first direction D1 b is preferably equal toor less than the width Wh of the compressor 2 in the first direction D1as shown in FIG. 2. The width Wh is a width in the first direction D1from the fourth inner face 41 d to the end of the compressor 2 in theone of the first direction D1 a. By setting Dh≤Wh, it is possible toprevent the width of the cooling system 100 in the first direction D1from becoming longer than the width when considering the size of thecompressor 2. Therefore, space of the cooling system 100 can be morereliably saved.

Next, a first modification of the example embodiment will be described.Hereinafter, a configuration different from that of the above exampleembodiment will be described. Moreover, components which are similar tothose in the above example embodiments are denoted by the same referencenumerals, and a detailed description thereof will be omitted.

FIG. 3 is a perspective view showing a configuration example of thecooling system 100 according to the first exemplary modification of thepresent disclosure. In FIG. 3, the cabinet 4 is shown in a transparentmanner for easy understanding of the structure. In FIG. 3, thedirections of the one of the first direction D1 a and the other of thefirst direction D1 b is opposite to those of FIG. 1. That is, in FIG. 3,the one of the first direction D1 a is directed downward in the drawing,and the other of the first direction D1 b is directed upward in thedrawing.

In the first modification, the one of the first direction D1 a isdirected vertically downward, and the other of the first direction D1 bis directed vertically upward. The first inner face 41 a of theaccommodation chamber 41 is the bottom face, of the accommodationchamber 41, that is directed vertically upward, and is orthogonal to thevertical direction. The fourth inner face 41 d is a ceiling face, of theaccommodation chamber 41, that is directed vertically downward. Thecompressor 2 is installed on the first inner face 41 a. That is, in thefirst modification, the first inner face 41 a is an installation face ofthe compressor 2 and is parallel to the horizontal plane. Thedefinitions of these faces are definitions for use in the description inthe present specification, and do not indicate the faces whenincorporated in an actual device.

In the first modification, the radiator 1 is disposed vertically belowthe blower 3. The compressor 2 is disposed in the one of the seconddirection D2 a relative to the radiator 1 and the blower 3. Further, theblower 3 sucks air from vertically below and sends out the airflow in adirection parallel to the horizontal plane.

By disposing the radiator 1 vertically below the blower 3 and disposingthe compressor 2 in the one of the second direction D2 a relative to theradiator 1 and the blower 3, the blower 3 that suck an airflow fromvertically below and sends out the airflow in a direction parallel tothe horizontal plane, and the radiator 1 and the compressor 2 cooled bythe blower 3 can be disposed in a compact manner. Therefore, the widthof the cooling system 100 in the first direction D1 can be furtherreduced without requiring downsizing of the blower 3. Therefore, thespace of the cooling system 100 can be saved without reducing the amountof air blown by the blower 3.

Next, a second modification of the example embodiment will be described.Hereinafter, a configuration different from that of the above exampleembodiment and the first modification will be described. Moreover,components which are similar to those in the above example embodimentsand the first modification are denoted by the same reference numerals,and a detailed description thereof will be omitted.

FIG. 4 is a perspective view showing a configuration example of thecooling system 100 according to the second exemplary modification of thepresent disclosure. In FIG. 4, the cabinet 4 is shown in a transparentmanner for easy understanding of the structure. In FIG. 4, thedirections of the one of the first direction D1 a and the other of thefirst direction D1 b are the same as those of FIG. 1. In other words, inFIG. 4, the one of the first direction D1 a is directed upward in thedrawing, and the other of the first direction D1 b is directed downwardin the drawing.

In the second modification, the one of the first direction D1 a isdirected vertically upward, and the other of the first direction D1 b isdirected vertically downward. The first inner face 41 a of theaccommodation chamber 41 is a ceiling face, of the accommodation chamber41, that is directed vertically downward. The fourth inner face 41 d isthe bottom face, of the accommodation chamber 41, that is directedvertically upward, and is orthogonal to the vertical direction. Thecompressor 2 is installed on the fourth inner face 41 d. That is, in thesecond modification, the fourth inner face 41 d is an installation faceof the compressor 2 and is parallel to the horizontal plane. Thedefinitions of these faces are definitions for use in the description inthe present specification, and do not indicate the faces whenincorporated in an actual device.

In the second modification, the partition 5 further includes aconnection member 52. The connection member 52 can be, for example, madeof a cushioning material such as sponge, or an elastic material such asrubber.

The connection member 52 is connected to the end of the panel 51 in adirection orthogonal to the second direction D2, and at least one of theinner face, of the accommodation chamber 41, that is directed to adirection orthogonal to the second direction D2 and the end of theblower 3 in a direction orthogonal to the second direction D2.

In particular, in the second modification, preferably, the end of thepanel 51 in the first direction D1 is indirectly connected to at leastone of the first inner face 41 a and the end of the blower 3 in the oneof the first direction D1 a. For example, the end of the panel 51 in thefirst direction D1 is connected to at least one of the above via theconnection member 52 as shown in FIG. 4.

Further, the end of the panel 51 in the third direction D3 orthogonal tothe first direction D1 and the second direction D2 is preferablyindirectly connected to at least one of the second inner face 41 b, ofthe accommodation chamber 41, that is directed to the one of the thirddirection D3 a, the third inner face 41 c, of the accommodation chamber41, that is directed to the other of the third direction D3 b, and theend of the blower 3 in the third direction D3. For example, the end ofthe panel 51 in the third direction D3 is connected to at least one ofthe above via the connection member 52 as shown in FIG. 4.

For example, the end of the panel 51 in the one of the first directionD1 a is preferably indirectly connected to the first inner face 41 a.That is, the end of the panel 51 in the one of the first direction D1 ais connected to the first inner face 41 a via the connection member 52as shown in FIG. 4.

Further, for example, the end of the panel 51 in the other of the firstdirection D1 b is indirectly connected to the fourth inner face 41 d.That is, the end of the panel 51 in the other of the first direction D1b is connected to the fourth inner face 41 d via the connection member52 as shown in FIG. 4.

Further, for example, the end of the panel 51 in the one of the thirddirection D3 a is indirectly connected to the third inner face 41 c.That is, the end of the panel 51 in the one of the third direction D3 ais connected to the third inner face 41 c via the connection member 52as shown in FIG. 4.

Further, for example, the end of the panel 51 in the other of the thirddirection D3 b is indirectly connected to the second inner face 41 b.That is, the end of the panel 51 in the other of the third direction D3b is connected to the second inner face 41 b via the connection member52 as shown in FIG. 4.

The opening 51 a of the panel 51 is preferably indirectly connected tothe exhaust port 32 b of the blower 3. For example, the opening 51 a ofthe panel 51 is connected to the exhaust port 32 b of the blower 3 viathe connection member 52 as shown in FIG. 4.

In this way, by connecting the panel 51 to the inner face, of theaccommodation chamber 41, that is directed to the direction orthogonalto the second direction D2 via the connection member 52, the panel 51can be easily attached to the inside of the accommodation chamber 41.Further, it is possible to more reliably prevent the airflow that hascooled the compressor 2 from passing between the panel 51 and the innerface of the accommodation chamber 41, and returning to the surroundingsof the radiator 1 and to the intake port 32 a.

Furthermore, it is easy to connect the opening 51 a of the panel 51 tothe exhaust port 32 b of the blower 3. In addition, it is possible tomore reliably prevent the airflow that has cooled the compressor 2 frompassing between the opening 51 a of the panel 51 and the exhaust port 32b of the blower 3, and, returning to the surroundings of the radiator 1and to the intake port 32 a.

Next, a third modification of the example embodiment will be described.Hereinafter, a configurations different from that of the above exampleembodiment, the first modification, and the second modification will bedescribed. Moreover, components which are similar to those in the aboveexample embodiment, the first modification, and the second modificationare denoted by the same reference numerals, and a detailed descriptionthereof will be omitted.

FIG. 5 is a perspective view showing a configuration example of thecooling system 100 according to the third exemplary modification of thepresent disclosure. FIG. 6 is a cross-sectional view of the coolingsystem 100 according to the third exemplary modification of the presentdisclosure when viewed from the other of the second direction D2 b. InFIG. 5, an imaginary plane Pa2 indicated by a broken line is parallel tothe first direction D1 and the third direction D3. Further, in FIG. 5,the cabinet 4 is shown in a transparent manner for easy understanding ofthe structure. In addition, FIG. 6 shows a cross section of the coolingsystem 100 when viewing the other of the second direction D2 b. In FIG.6, the space between the radiator 1 and the compressor 2 in the seconddirection D2 is imaginarily cut by a plane Pa2. Further, in FIG. 6, thecompressor 2 is indicated by a broken line, and a wall portion 43 andthe partition 5, which will be described later, are shown in atransparent manner for easy understanding of the structure. In FIG. 5,the directions of the one of the first direction D1 a and the other ofthe first direction D1 b are the same as those of FIG. 1. That is, inFIG. 5, the one of the first direction D1 a is directed upward in thedrawing, and the other of the first direction D1 b is directed downwardin the drawing. Further, the arrangement of the radiator 1, thecompressor 2, and the blower 3 in the accommodation chamber in the thirdmodification is the same as that in the above example embodiment and thesecond modification.

In the third modification, part of the cabinet 4 protruding from thefirst inner face 41 a of the accommodation chamber 41 when viewed fromthe other of the second direction D2 b overlaps with the radiator 1, andpreferably overlaps with the entire radiator 1.

For example, as shown in FIG. 5, the cabinet 4 further includes the wallportion 43 provided between the partition 5 and the first inner face 41a. The wall portion 43 protrudes from the first inner face 41 a in theone of the second direction D2 a relative to the radiator 1 and in theother of the second direction D2 b relative to the compressor 2. Thewall portion 43 extends in a direction intersecting the first directionD1 and the second direction D2. In the third modification, the wallportion 43 protrudes from the first inner face 41 a to the other of thefirst direction D1 b. Furthermore, the wall portion 43 extends in thethird direction D3. However, the present disclosure is not limited tothis example, and the wall portion 43 may extend in a directionintersecting with the third direction D3 at an acute angle.

In the second direction D2, the accommodation chamber 41 is partitionedby the wall portion 43 and the partition 5. In the third modification,the wall portion 43 partitions part of the space between the radiator 1and the compressor 2, and the partition 5 partitions the remaining partthe space between the radiator 1 and the compressor 2. In theaccommodation chamber 41, the compressor 2 is disposed in the space inthe one of the second direction D2 a relative to the wall portion 43 andthe partition 5. Furthermore, the radiator 1 and the blower 3 aredisposed in the space in the other of the second direction D2 b relativeto the wall portion 43 and the partition 5.

The wall portion 43 overlaps with the radiator 1 when viewed from theother of the second direction D2 b. Preferably, as shown in FIG. 6, thewall portion 43 overlaps with the entire radiator 1 when viewed from theother of the second direction D2 b. Since the wall portion 43 overlapswith the entire radiator 1, it is possible to prevent the airflow blownfrom the blower 3 to the compressor 2 from flowing to the surroundingsof the radiator 1. Therefore, it is possible to prevent the airflow thathas cooled the compressor 2 from returning to the surroundings of theradiator 1. Therefore, the blower 3 can cool the radiator 1 moreefficiently.

Preferably, as shown in FIG. 6, the end of the wall portion 43 in theone of the third direction D3 a is connected to the third inner face 41c, and the end of the wall portion 43 in the other of the thirddirection D3 b is connected to the second inner face 41 b. Therefore, itis possible to prevent the airflow that has cooled the compressor 2 frompassing between the wall portion 43 and the inner faces 41 b and 41 c,of the accommodation chamber 41, that is directed to the third directionD3 in the first direction D1, and returning to the surroundings of theradiator 1 and to the intake port 32 a.

In addition, the partition 5 is provided in the other of the firstdirection D1 b relative to the wall portion 43. In the thirdmodification, the panel 51 is provided. Preferably, as shown in FIG. 6,the end of the wall portion 43 in the other of the first direction D1 bis directly or indirectly connected to the end of the partition 5 in theone of the first direction D1 a. Therefore, it is possible to preventthe airflow that has cooled the compressor 2 from passing between thewall portion 43 and the partition 5 in the first direction D1, andreturning to the surroundings of the radiator 1 and to the intake port32 a.

In the example embodiment and the modification described above, thecompressor 2 is installed on the bottom face of the accommodationchamber 41 that is parallel to the horizontal plane and directedvertically upward. Specifically, in the above example embodiment, thesecond modification, and the third modification, the compressor 2 isinstalled on the fourth inner face 41 d that is parallel to thehorizontal plane and directed vertically upward. In the firstmodification, the compressor 2 is installed on the first inner face 41 athat is parallel to the horizontal plane and directed vertically upward.However, the present disclosure is not limited to these examples, andthe compressor 2 may be installed on the inner face other than the firstinner face 41 a and the fourth inner face 41 d in the accommodationchamber 41. However, even in this case, the relative positionalrelationship among the radiator 1, the compressor 2, and the blower 3 ismaintained. Such a positional relationship can be easily understood byreplacing the first direction D1, the second direction D2, and the thirddirection D3. For example, when the compressor 2 is installed on theinner face 41 b or 42 c directed to the third direction D3 in theaccommodation chamber 41, “the first direction D1” in the above exampleembodiments and the modifications is read as the third direction D3, and“the third direction D3” in the above example embodiments and themodifications is read as the first direction D1. In this case, thesecond direction D2 need not be replaced. Even with such modifications,the same effects as those of the above example embodiments and themodifications can be obtained.

The present disclosure is useful, for example, in a system in which ablower cools a radiator and a compressor.
